Do not call this number!
They are complete and utter scammers! They took advantage of my parents and hacked into their home computer.
When I rang them to ask what company they worked for they said 'I can not give you that information'. I persisted to get any information about who they are and what authority they have to 'fix' a computer and got promptly hung up on.
DO NOT CALL THESE SCAMMERS!
If you do let them onto you computer be sure to take it to a computer repairer to get whatever malware they installed wiped off.

This is a number involved with a computer scam. From "s3-us-west-2.amazonaws.com" they freeze your browser, refer you to this number and try to scam you out of money. There is nothing wrong with your computer, there is no virus or malware involved. It is referred to as 'scareware'. I have checked further and found these people are involved with al-qaeda and ISIS.
